Details and patient eligibility

About

The purpose of this study is to evaluate the efficacy, safety and tolerability of balcinrenone in fixed combination with dapagliflozin, compared with dapagliflozin, in patients with CKD Stage 3b and 4 (eGFR ≥ 15 to < 45 mL/min/1.73 m2) administered orally once daily in addition to SoC.

This is a population with high unmet medical need and an increased risk of CKD progression, who are frequently excluded from interventional trials.

Full description

This is a Phase III, multicentre, randomised, double-blind, double-dummy, parallel-group, active-controlled, event-driven study in participants with CKD Stage 3b and 4.

The purpose of this study is to determine if balcinrenone/dapagliflozin, compared with dapagliflozin, administered as a capsule once daily on a background of standard of care (SoC) therapy, reduces the risk of CV death, death from kidney failure, kidney failure, sustained ≥ 50% decline from baseline in eGFR, and HF events in adults with CKD Stage 3b and 4. The study will also assess safety and tolerability of balcinrenone/dapagliflozin.

Eligible patients will randomly be assigned with a 1:1 ratio to receive once daily administration of one capsule and one tablet of one of the following treatments:

1. Balcinrenone/dapagliflozin 15 mg/10 mg capsule and matching placebo for dapagliflozin 10 mg tablet
2. Dapagliflozin 10 mg tablet and matching placebo for balcinrenone/dapagliflozin capsule The study will be conducted at approximately 550 sites in approximately 30 countries, globally.

Enrollment: 2,800 estimated patients

Sex: All

Ages: 18 to 99 years old
